BRONZING MACHINE Filed July 27, 1928 e729@ @Mm Q) @Wo/sg Patented Sept. 20, 1932 Unirse stares PATENT ortica FRANK R. BELLUCHE, F RACINE WISCONSIN BRONZING MACHINE Appiieation ined July 27,1928. serial No. 295,718.

This invention relates to means for increasing the eiiiciency of eXhausters used in connection with bronzing machines.

In bronzing machines it is customary to provide an exhauster for drawing olf excess bronzing material and while this method functions satisfactorily, it has been found that much of the material becomes lodged on the bottom of the machine where it'reinains,

; and therefore, it is an object of this invenf ,i of the eXhauster.

And a more specific object of this invention resides in the provision of means for ,connecting the interior of a bronzing machine with the air outlet of a cyclone or separating receptacle whereby both suction and pneumatic pressure are employed to thoroughly remove all of the excess material from the interior of the machine.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel con- .F struction, combination and arrangement of VVparts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the' ,hereindisclosed invention may be made as come within the scope of the claims. Inv the accompanying drawing,

4ical embodiment of my invention constructed 'i110V- machine embod'iino m invention with' D 5 o y i portion of the cyclone and is provided with vised for the practical application of the principles thereof, and in which:

The single view is an end view of a bronzparts thereof broken away and in section.

Referring now more particularly to the accompanying drawing, in which like. nu-

Vbronzing material falling downwardly to the 7 bottom 9 of the machine.

I have illustrated one complete example of the physmerals designate like partsjtliroughout the;

`several views, 5 and 6 ldesignate the vside frames of a bronzing machine of that type lmore at length described in my copending application, Serial No. 285,030 filed JunelS, The side frames are maintained in proper spaced relation by any suitable means including cross bars and the like, not shown, and rotatably mounted therebetween are the various work carrying cylinders, of which the bronzing cylinder 7 and a plurality of cleaning ro-lls Spare only shown.V

Inasmuch as the particular construction of the bronzing machine and the manner in which the work is fed through themachine has no part in this invention, the saine is not shown nor described, suffice it to say that the cleaning rolls 8 remove the excess bronze from lthe sheets or work as they are carried past them by the bronzin'g cylinder 7, the excess 'The side frames 5 and 6 are provided with 4similar openings 10 and 11 in line with the bottom 9, the Yopening 10 communicating with an eXhauster 12 through a passage 1.3 formed 75 by a box-like structure 14 secured to the side' frame 5by screws or the like 15. The eX- hauster 12 is mounted in any 'suitable manner and is` driven by a drive belt, not shown, trained about a pulley 16.

Connected with the outlet of the exhauster is a duct or tube 17 which extends upwardly to have its discharge end 18 communicate with the upper portion of a cyclone orseparator 19 of conventional construction. A. i bracket 20'secured to the side frame 5 suitably supports the cyclone and a second bracket 21 likewise secured to the sideV frame carries an adjustable supporting means 22 at its outer end to maintain a container 23 directly kbeneath the lower end of the cyclone '19.. As

is well known, the cyclone 19 functions to separate the air and bronzing material discharged into it by the eXhauster. n An air outlet 24 is formed at the upper two ducts 25 and 26 equipped with a damper 27 Varranged to regulate the draft through the duct 26. The duct 25 opens to the atmrosv-A 100 soV phere and the duct 26 has its opposite end connected with the opening ll in the side frame 6 to communicate with the interior of the bronzing machine. As will be readily apparent, a pressure current of air is forced into the interior of the bronzing machine which assists the suction of the exhauster to thoroughly remove the excess bronzing material in the machine, the damper' 27 beingv adjustable to regulate the, proportion of air passing through the duct 26 to that being discharged through the outlet 25.

If desired, a false bottom 28 may be pro vided consisting of a plurality of angularly v which utilizes the normal air discharge ofthe cyclone or separator. v

What I claim as my invention is: 1. In a'machine for applying powdered material to work passed through (the machine, the excess of materialbeing removed ,y from the work, a'plurality of spaced elements upon which the excess material drops, means for producing `a vacuum to draw the excess material fromr the machine, means for conducting a pressure current of air overand under the spaced elements, and saidspaced elements being inclined to bias the pressure current of air upwardly 'to assist the vacuum .means in drawing the excess material from the machine.

2. In a machine for applying powdered material to work passed through the machine, the excess of material being removed from the work, a plurality of spaced slats f upon which the excess material falls,'means for producing a vacuum to draw the excess materlal from the machine, means for conducting a. pressure current of air over and l beneath the plurality of spaced slats, and

said slats being inclined at anl upward angle e to bias the pressure-current of air passing over and beneath them upwardly to assist they vacuum means in removing excess material from the machine.

3. A device to collect bronzing dust comprising a chamber in Awhich the'dust is collected, having an opening in the lower portion thereof, a draft creating means producing Va stream of air, and having an intake thereof connected with said opening for Vr'vithdrawing dust from said chamber, a dustV separator connected with said means for receiving dust and separating it from the' stream of air, means'for returning the air stream from the separator to the lower portion of said chamber, and means in the lower portion of said chamber for agitating the returned air to assist in the removal of the dust. Y l

4. A device to collect bronzing dust comprisin'ga chamber in which the-dust is col-, lected having an opening in the lower portion thereof, a draft creating means producing a stream of air, and having the intake thereof connected with said opening for Withdrawing fdust'from said chamber, a dust separator connected with said means forreceiving the dust and separating it from the stream of air means for returninoF the' air stream from the separator to the lower portion of said chamber, means in the lower, portion of said chamber for agitating the returned air to assist in the removal of the dust, and means to regulate the force of said returned air.

` 5. A device to collect bronzingv dust comprising a chamber in which the dust is collected having an opening in the lower portion thereof, a draft creating means producing a stream of air, and having therintake thereof I er portion of said chamber to direct said re- Vturned air upwardly to agitate the dust.
